High Performance Self-Adhered Flashing with

Non-Asphaltic Butyl-Modiﬁed Adhesive

The Better the Seal, the Better the

Performance

The primary purpose of a ashing tape is to prevent the

migration of water and air through window and door

openings. Product performance depends on the adhe-

sive bond between the ashing and the substrate. This

is especially true for irregularly surfaced materials such

as OSB. The better the adhesive seals itself into the

peaks and valleys of the substrate, the better the barrier

against water and air migration.

Moisture Control is the First Step to

Mold Control

Water from both exterior and interior sources is among

the worst enemies of building structures. When mois-

ture enters and remains within the wall system, it

creates a favorable environment for the development of

rot, mold and mildew. Repairing these types of prob-

lems can be very difcult and extremely costly.

Air Control is the First Step to Better

Energy Performance

The key to optimizing energy performance is prevent-

ing the movement of air both into and out of the

building envelope. Air leaks around window and

door openings make it difcult to keep a comfortable

indoor environment, forcing the HVAC system to work

harder, while driving up energy costs.

A properly integrated ashing tape that adheres and

seals aggressively to the substrate will create the most

effective barrier against water and air migration while

acting as a drainage plane to shed water down the exte-

rior of the building envelope.

What Makes Vycor

PRO Flashing

Different?

Grace Vycor

PRO ashing, with its unique lm and

non-asphaltic, butyl-modied adhesive technology,

provides premium protection against water inltra-

tion in all critical non-roof detail areas, that traditional

building papers, felts, housewraps and other ashing

products cannot match.

Product Advantages

• Creates a superior barrier against air and water

intrusion

• Optimizes energy performance

• Wide application window for

installation ﬂexibility

• 120 days of exposure provides

work scheduling ﬂexibility

• Compatible with rigid and

ﬂexible PVC window nailing ﬂanges

In addition, Grace Vycor

PRO’s wide application and

service temperature windows make it appropriate for

use in any environment.

Product Description

Vycor

Pro ashing is composed of a durable, tear and

puncture resistant engineered polypropylene backing

lm, paired with an aggressive, non-asphaltic, propri-

etary butyl-modied adhesive. Grace Vycor

PRO

ashing comes in 75 ft rolls and is available in:

4 in. (102 mm)

6 in. (150 mm)

9 in. (225 mm)

12 in. (305 mm)

in-service conditions up to 176° F (80° C)

• Longexposuretime—120 days of exposure

provides protection over long, unpredictable

construction cycles

• FlexibleApplication—Grace Vycor

PRO’s wide

performance window makes it appropriate for use in

all regions

• Easytoworkwith—This high performance barrier

membrane is easy to apply with 6 and 12 inch (150

mm and 305 mm) measurement markings.

• SuperiorWeatherProtectionSolution—Use in

combination with Grace Vycor

Compatibility

•Vycor

®

Pro ashing contains no asphalt, and is fully

compatible with rigid and exible PVC window

nailing anges.

•Compatible with common weather resistive barriers

and many types of sealants. Refer to Technical Letter

1, Chemical Compatibility with Other Building Mate-

rials and Sealants for more information.

Usage

Grace Vycor

PRO ashing is a unique solution

appropriate for working around a number of detail

areas, including, but not limited to:

• Window and door openings (headers, sills, jambs,

thresholds, nailing anges)

• Deck-to-wall intersections

• Corner boards

• Wall-to-wall tie-ins

• Foundation sill plates

• Sheathing panel seams

• Under stucco nishes

• Masonry walls

• Application to EPDM in vertical applications

• Other non-roof detail areas

Application Instructions

Apply in fair weather to clean and dry surface at air

temperatures of 25°F (4° C) or higher. Apply directly

to substrate. Compatible substrates include wood,

plywood, oriented strand board, exterior gypsum,

metal, concrete and masonry. Install Grace Vycor

PRO ashing with weather-resistive barriers to form

water-shedding laps. Cut membrane to length. Peel

back release liner. Align membrane and press into

place. Mechanically fasten membrane at vertical termi-

nations as necessary. Press or roll into place with hand

roller to achieve best adhesion. Primer is generally

not required for most substrates (including plywood,

OSB, dimensional lumber, PVC window anges, steel,

and aluminum) provided they are clean and dry. On

concrete, masonry and glass ber surfaced gypsum

sheathing apply Perm-A-Barrier

WB Primer at a

coverage rate of 250–350 ft

/gal (6–8 m

/L). Regard-

less of substrate, if adhesion is found to be marginal,

prime substrate material with Perm-A-Barrier

Primer at the same coverage rate.

Precautions & Limitations

SLIPPERY—DONOT install on the roof. Do not

leave permanently exposed to sunlight. Maximum

recommended exposure is 120 days. May be applied to

EPDM in vertical applications. Some caulks containing

high levels of hydrocarbon solvents may be incompat-

ible with the adhesive in Grace Vycor

PRO ashing.

Check with the caulk manufacturer or your local Grace

representative and/or refer to Grace Technical Letters

on the Grace web site.

Approvals

• Meets AAMA 711-13 specication for

self-adhered ashing Level 3 requirement for

elevated temperature exposure.
